I would like to make some small changes on a booking for calendar right now.

Hell there,
We hire someone in here to make some changes on our taxi booking form calendar, but all they have been doing for the past week is to find reason, and not fix the issues they are hired for. So if you are one of those people, please do not send a proposal.

Issue:

1. The calendar has a departure time, and round trip time.
2. We would like to set the round trip time 3 hours ahead.
I will need to add you on Skype so I can show you the form. We need this job done within hour, since it's quite small changes.

right now, it's showing a - sign.

Cheers,
Jeremie
